A quick comparison of noise levels relative to the Niche, both with and without beans. Basically the Niche runs at around 70db dry with the KEY around 55db. With beans, both grinders set to the same level for espresso, the Niche is at 76-78db while the KEY runs at 68-70db. The KEY is down at the lower end of the RPM spectrum where the grind rate is similar. If the KEY is revved up, the noise levels are more on par with the KEY, but it is also grinding much faster.
